The funny thing is Megas were created a little after, since originally they ended at Ultimate, which makes sense when you remember Digimon started off as a male focused counterpart to Tamagotchi, which only has 5 stages to its own evolutions

Even the Japanese name for the evolutions Baby I > Baby II > Child > Adult > Perfect

Leads to a funny situation since their Mega name is Ultimate, nothing like confusion
