Here's a concept I've been wanting to show off for a while now, and that's Overdrive Lowan.
This form is basically Lowan, but powered up via Etheria (magic) energy.
In this state, his strength, magic prowess, and speed are increased drastically.
However it can become a detriment, he can only maintain this form for 15 minutes, any longer and his body will either burn out and perish, or... explode lol.
Either way, he can't stay in it for long and it makes him exhausted after using.
