Compared to the likes of Hank and Sanford, Deimos seems to take his job less seriously, as illustrated when he flashes an agent a "Rock On" sign while killing him in Madness Combat 5.5 when he jokingly tries to scare Sanford by donning an A.T.P. mask and waving around a carbon knife in Madness Combat 9, when he dances before stealing the sunglasses of an agent which he then kills and later he dabs before brutally killing another agent again in DedmosRebuilt.fla when he taunts an agent by pointing at him after sticking a baton into his head in that same episode, and when he made and won a bet with Sanford in Incident: 100A. His carefree nature is especially shown in MADNESS: Project Nexus, where, for example, he asks Bandits to “move along and dance for another day”. When Sanford explains how the Bandits will eat their bodies if they are defeated, he says Sanford would be a ”big kielbasa” to them.

It is implied through text in POWERLESS.fla that Deimos is not very bright, as if he had taken the time to examine his surroundings and situation instead of rushing in, he would not have met his fate at the end of the short. In the next episode it's shown that he uses 8520 as his password, which on a standard numpad is input by swiping a line from top to bottom. Lastly, posters set about by 2BDamned chastise him for being impatient and impulsive.

It is also implied in SACRIFICE.fla that Deimos is very flippant and disinterested. As he falls perpetually through Purgatory he simply acts annoyed and smokes a cigarette rather than demonstrate any fear.

He also seems to have a higher pain tolerance than Sanford, as shown in ANAMNESIS.fla, and SACRIFICE.fla, that his jaw, and many other parts of his face, are missing. However, while it seems that he is not in pain, Krinkels confirmed that "He felt pains of all varieties" while being in the purgatory dimension. Also shown in Madness Combat 5.5, Deimos survived being crushed by the Flying Party but was also shown to be in little, to no pain. Deimos, like Sanford and Hank, is very skilled in combat, as his profession requires him to be. However, unlike the more melee-savvy Sanford, Deimos prefers to use firearms and even explosives where he can. This skill was especially useful in their earlier involvement in the story, where Deimos had to protect an injured Sanford until he could recover. His skill in firearms is at a point where he can accurately fire dual-wielded G36 assault rifles or an MG-42 from the hip with ease, a task that would be very difficult for most. His skill in explosives often sees him equipped with such weapons as the M203, flashbangs, or time bombs. All-in-all, his proficiency with ranged weapons and explosives allowed him to maintain a higher kill count than Sanford up until his death. His fighting style typically involves him taking the lead and charging in, without very much strategy. Given that this style is very similar to the fighting styles utilized by AAHW units, Deimos's fighting style was likely learned from his time in the agency. Another flaw he may have gained from the agency is his occasionally slow reaction time, which allowed him to be blinded by a flashbang and "Sanford" to be shot by an ATP Soldat. He failed to react to an enhanced ATP engineer entering the room in time, which would ultimately prove fatal for him.

Deimos's most useful ability is his knowledge in the field of technology. From Madness Combat 7.5 onward, Deimos would be equipped with a headset, communications backpack, and PDA. The PDA was used to receive instructions for the team, and his headset and com-pack were utilized in Madness Aggregation to confirm with an unknown person that they had located Hank. With his former employment and experience in the AAHW, Deimos proves useful when it comes to accessing their technology, having been observed to input a code to unlock spike gates, using a terminal to get directions around a facility, and even being capable of using an Agent Magnification Chamber to revive and enhance Hank. Deimos is also often the driver of the two, driving their convertible, a truck, and even being capable of flying helicopters. Though not seen driving it, it is possible that he owned the sedan seen at the beginning of Madness Aggregation, given his angry reaction at its destruction; it's possible Sanford was driving so that Deimos could operate the tracking equipment. He also seems to possess somewhat incredible luck, escaping four near-death scenarios: being crushed by the Flying Party, nearly being crushed by another building, nearly being shot in the head by the engineer that shot Sanford, and accidentally dodging two potentially fatal shots from an A.T.P. soldat after being blinded by a flashbang.

Initially Deimos, like Sanford, contained no special powers. He, along with Sanford, were ordinary grunts who just handed Hank a weapon. However in the spin-off series Dedmos Adventure, which chronicles his experience in Purgatory, Deimos changes significantly in the final episode, DedmosRebuilt.fla. After having his body continually broken down for the prior four episodes, it is renewed with stone covering his jaw, chest, and hands. This enables him to deliver especially harder-hitting punches, capable of leaving severely deforming and often fatal marks on bodies bigger than his own. He also gains magic abilities, able to summon stone spikes from the ground, or even magnify people, as he might have done accidentally with FellowD9. His endurance has significantly boosted, as he can now get up and fight fine after being slammed into walls hard enough to leave a crater. His agility and perception were also increased, as he is seen dodging punches, blows, and chains, and delivering hard hits with extreme ease. He can throw around enemies larger than him, spin, bicycle, drop-kick, and even slam or stomp enemies hard enough to firmly embed them into walls or floors. With all of this, Deimos' overall abilities in hand-to-hand and melee combat put him up to a level comparable to, if not greater than Mag Hank. However, given that this all occurs in Purgatory, it is unknown if these powers and abilities transferred with Deimos when he was brought back to Nevada.

If Deimos is completely drunk or extremely sleepy, he will keep talking and rambling about cigarettes.
