True Super Saiyan 4 (Imperfect)

True Super Saiyan 4 (Imperfect) is an imperfect version of True Super Saiyan 4 first used by Gohan: GT. It is an evolution of Super Saiyan 4 which can be obtain through any enhanced version of Super Saiyan 4.

Overview
After channelling energy while either in the Super Saiyan 4 or an enhanced variation the user can further evolve their Super Saiyan 4 state which usually sends them into a Power Stressed State which is often a brief transition before unleashing a whirlpool of energy that enables them to break through the limits using sheer willpower.

Eventually, their hair and fur will take on a salt and pepper colour while their hair becomes spikier. The user will also grow in height as their aura will gain a higher bio-electricity frequency almost as it is lightning shooting off the user.

Usage
Gohan first achieved this form while fighting against Eis Shenron and was able to utterly overpower the Super Shadow Dragon; he was able to defeat him with his Soaring Dragon Flash, but almost immediately after lost the form. It was deduced by Goku that Gohan could only maintain the form for a few minutes either due to inexperience of them form or if its the form's natural time limit.

True Super Saiyan 4
True Super Saiyan 4 is the complete and perfected version of True Super Saiyan 4. Gohan was able to achieve it during his fight with Syn Shenron and was later again achieved by Xeno EX Kakatz.
