stepfather Steve Dayton, AKA Mento, used a helmet he designed to give
himself mental abilities. He did this to
try to impress and woo actress Rita Farr, known at the time as
after the murderers of the Doom Patrol were found, Dayton only used his helmet
sporadically. However, with later times, Dayton also began to
periods of dementia and madness, apparently connected to his use of the
helmet. At one point, Vernon Questor, Dayton’s
business manager, informed Gar that repeated use of the helmet was
killing Dayton. He was later
cured by Raven. Dayton
experienced other periods of madness, until his final one where he
helmet tampered with at some point?
General Zahl did
something to the Mento helmet.
Titans rescued Dayton
from General Zahl (an old Doom Patrol enemy), Dayton
kept insisting he have his Mento costume (this was the blue and yellow
outfit). As soon as Dayton
put it on, he attacked the Titans (stopping when Raven used her powers
him). However, Zahl only had access to
one of Dayton’s helmets, not the
plans or the early model helmets. Later
periods of madness were with different versions. At one point,
Gar tried to use an early Mento
helmet, which seriously affected his shapeshifting powers.
Chief (Niles Caulder) tampered with either the helmet
or the plans.
the time that Dayton
spent around the Doom Patrol, the Chief had access to the Mento helmet,
possibly the plans as well. The
inclusion of a rogue circuit at some point might have carried over
various models of the helmet without Dayton
knowing exactly what it was for.
a nice guy that brought together the Doom Patrol, right?
in the 3rd Doom Patrol series,
revealed that Caulder had actually been responsible for the accident

entirely possible that Caulder saw an easy opportunity
to add another person to his trial group.
factor behind the idea that the Chief is responsible
goes back to Dayton’s behavior
during one of his episodes. At one
point, Dayton confined himself to
wheelchair, as the Chief had been, acted like he was the Chief, and
experimented on people (eventually creating the Hybrid). For

Now, thanks to
the "Superboy Prime Punch," Steve Dayton has returned to the DCUniverse
AND has returned as Mento. HOWEVER, after his return, apparently
Mento was "confused" and "obsessed", refusing to take his helmet off
based on things he had been told by the Chief. When Steve finally
took off the helmet, his thinking was much clearer. Basically, he
returned to his "old self." I find this supports my initial
theory that the Chief messed with the Mento helmet.
