Strong verbs form a past tense by shifting an internal vowel while weak verbs take the suffix "-ed." Neither of these account for "login" becoming "logged in" as a past tense. If the language has evolved then we must consider a new verb type of regular verb.
They also come in many forms. Just as Voltron has both vehicle and lion forms, the voltron verbs have irregularities, like how "login" becomes "logged in" but "cutover" becomes "cut over" instead of "cutted over." Voltron can combine using different vehicle components, and voltron verbs combine using different preposition components. Notice, too, that they are strongest when combined; the imperative form for "login" and "shutdown" are "login" and "shutdown," respectively. In that same way, Voltron is invincible when combined. Finally, Voltron is the pinnacle of modern, but is an ancient technology that was resurrected by young fighters to defend Arus. The parallel with voltron verbs is obvious, considering their component parts are all old words wielded by young people on web pages.
