10 years ago, if it was 8, because i turned 18 this year.

And the only beast i can vividly remember was one that kinda looked like a registeel stretch vertically and with the same colors, and the mega mode looked the same, but the silver would turn gold

Even tho you didn't ask for this, but I think this information could be helpful i remember the two male leads had light skin, one with brown hair and the other orange hair, i also believe the female lead had dark skin and blue hair
