@thetransformerfreak i thought of a second form for ralph
Hēi’àn de zhènzhōng Ralph
Its complicated, but Hēi’àn de zhènzhōng translates directly to Dark Epicenter. I was too lazy to make a figure.

Attacks:
Cant evade, because stuck to the ground.

Attack 1: extends arm to hit the ground. Does great AOE damage, and poisons.
Attack 2: roars, summoning enemies.
Attack 3: roars in a different way, slowing down the player.
Attack 4: Hēi’àn de zhènzhōng ralph puts his hands in the air, and charges a ball of dark energy, and throws it to the ground. Does alot of AOE, and temporarily blinds the player, though this attack is rare.
Attack 5: shoots dark vines from his arms in different directions, they land on whatever they come in contact first. They stick to walls, and poison the player if touched. If they hit the player instead of a wall when shot, it grapples them to Hēi’àn de zhènzhōng ralph, and he punches you, knocking you to the wall and doing alot of damage.
Attack 6: his eyes shoot high damage lasers that move across the floor.

How do you defeat this behemoth? Every once and a while, a small sparkle of light will appear. If you touch it, your weapon becomes charged up and deals 1 damage to Hēi’àn de zhènzhōng ralph. If your weapons not charged, it does no damage. Hēi’àn de zhènzhōng Ralph has 5 health, which means it’d take 5 charged hits to defeat him. After each attack though, each enemy summoning roar summons more enemies.

I think this is worthy to be the final boss.
