the first 3 are designs for evil future randy
okay his story is:
so in randys final year of highschool the sorcerer escaped and randy not being strong enough turned to the only thing that had the power to stop the sorcerer the tengu he released it, and it tried to posses him but he overpowered it with sheer willpower(he fully absorbed the tengu and all its demonic powers) after a gruesome battle he defeated the sorcerer but the nomicon noticed that during his fight, randy was filled with more rage, blood lust etc. so when it learned of what randy did for more power it held him in trial, chastising him and telling him what he has now will corrupt his mind, randy flares shouting things like “I CAN CONTROL IT” while his flame powers spike. basically the nomicon locks him away in the sorcerers once prison. Randy escapes 10 years later bursts into weinerman industries(formerly mcfist industries) finds the old time mchine uses his demonic powers to travel to the past with the current ninja chasing after him. He goes to his 9th grade self to make the events that gave him his tengu powers happen sooner than it originally did, but not only that he was plannin to take his young self and posses him and rule the world with the philosophy of “The only way to make sure the bad guys dont take control is if I take control first, and wipe out anyone in my way”
oh and the last one is not evil older randy, who is just a normal dad who makes dad jokes.
