Like the pygmies of old human legends, minions are puny creatures, both physically and mentally, belonging to one of the most ancient and numerous races in the Tower. Their aspect vaguely resembles that of an edgy teen, since their stature rarely tops a metre and they love to wear hoodies and sneakers. It is said that this behaviour mimics that of magpies: everything that has been deemed cool by anyone, anywhere, becomes instantly an obsession for any minion who gets the news.
This is the reason why, some anthropologists believe, minions are easily swayed by anyone into serving for any cause, be it a grand liberation struggle or the theft of churros; thus people in the Tower never fully trust minions, who switch from being your best ally to being your worst enemy in a matter of seconds. The general rule is "He who feed the minion, controls him".
As previously stated, minions have been observed in the service of the worst baddies in the Tower: infamous are the Oculista's fearsome myopic and burger-flipping minions. It does seem, though, that most minions still resist the call of RAD's army; some say it's due to the extreme lack of coolness in this evil project (so much so that RAD had to resort and create bullycops to cope with the impending lack of manpower).
Regardless, many minions have heeded the call to fight for freedom and have joined Bendy Bandit's rebellion and man the crew of the speedy Mayhem Machine.
