Master Morpher Deku

Exactly what the title says. Izuku with the Master Morpher from Power Ranger, allowing him to transform between Green Ranger, White Ranger, Zeo Ranger V, Red Turbo Ranger and Black Dino Thunder Ranger.

His journey through the story would be to unlock the rest of the forms but most others besides Green have been damaged or unstable over the years and thus can't sustain transformation for more than a hand few of minutes or even seconds.

Zeo also has grown too strong over the decades and as a result it functions like OFA, damaging Izuku with each blow until he grows to manage the power. I don't think Zeo is as strong as All Might but it's pretty up there in terms of the strength department.

In combat, Green is his balanced Jack of all trades and his most stable form. White is basically a super mode and grants enhanced capabilities for a short period of time and tires him out after use. Red Zeo is for heavy hitting and focuses on power. Black Dino Thunder is defence orientated and able to tank more blows and red Turbo is for speed.

Just the barebone minimum stuff so far. Let me know what you think in the comments.
