Storm

Not to be confused with the unrelated Wither Storm. "Pathetic Maxor, just like expected. Don't boast about beating this simple minded Wither. My abilities are unparalleled, in many ways I am the last bastion. The memory of your death will be your fondest, focus up!"

- Storm, upon starting Phase 2

Storm is a along with Maxor, Goldor and Necron of The Catacombs in The Catacombs - Floor VII and is a disciple of the Wither King.

Lore
Disciples of the Wither King. Inherited the Catacombs eons ago. Never defeated, feared by anything living AND dead.

Boss Fight
The boss fight is split into four phases. (Five phases in Master Mode.) There are four Wither Lords: Maxor, Storm, Goldor and Necron. Each Wither will be a boss for a phase that must be killed individually for each phase.

In all parts of the boss fight, lava damages the player for 20% of their max health, as well as launching them upwards. When being launched by lava, the player has an unknown chance to launch much higher than usual.

Phase 2
This is known as Phase 2.

The factory's second layer is exposed. Storm will now fight after Maxor was defeated in Phase 1. This layer comprises a large hall; a main platform with 4 diorite crushers, an outer ring with control pads for the crushers in the corner, and a ring of lava in between. Wither Miners and Withermancers cover the area, with Wither Guards located on raised platforms. One Shadow Assassin guards each control pad. Storm will attempt to damage the player with lightning bolts within an area from fireballs thrown onto the ground. Storm will occasionally start a countdown, after which lightning will strike anywhere that is not under an intact crusher and deal small bursts of 8.5k true damage (Normal Mode), which can one-shot most players. Anything which keeps you alive after taking a fatal hit can negate the damage.

Standing on the control pads raises and lowers the corresponding crusher (except the red crusher, which is broken). When Storm is crushed by a pillar, he will be stunned and become vulnerable for 10 seconds. After this, he will enter an enraged state.

The next phase will begin when Storm has been crushed under at least two pillars (purple, green or yellow), and enough damage has been dealt to Storm. Failing to deal enough damage after crushing Storm with all three pillars softlocks the fight (but the amount of damage Storm deals is enough to kill all players.)
