Needle

In-Game Behavior
Needle summons a row of 4 spikes towards the closest person in her view as her main attack: she suffers a short cooldown for whenever she can summon spikes. She can also summon two circular rows of spikes around herself. At some point during the round, Needle gains the ability to summon a slow-moving, homing cone-shaped rocket that'll travel towards the closest player. When it makes contact with a player, it will explode and summon a circular pool of spikes. The spikes themselves are the only way for Needle to damage you; when you make contact with one, you'll take 25 damage and get pushed backwards.

EX Form
Needle's EX form gains the ability to move faster and summon red spikes. Red spikes are much more dangerous, as unlike the normal spikes, they'll insta-kill you. Needle also has 2 new attacks in her EX form, which are spike mines and mini spikes. Spike mines will hide in the ground, only appearing as a black circle to indicate where they are located. When you step on them, you'll suddenly be attacked by a red spike! Mini spikes on the other hand will be sent in 4 directions individually from Needle. They'll explode whenever they make contact with something.
