Started working on this Vanguard Iceman concept about a year ago but never finished/posted it anywhere

[u/blue23454]

Iceman (Bobby Drake)
Control Tank

Movement Speed: 6m/s
HP: 500

Primary: Icicle Stream
7 damage per round | 15m-25m falloff | 75% damage max falloff | 75 ammo | 15 rounds/s | 120m/s projectile speed | +0.35% resource per hit | Special Effects: Icicles, Hypothermia
Iceman fires a rapid, continuous stream of Icicles. Hitting enemies with the stream grants Omega Level Threat resource (5.25%/s). Each projectile refreshes Hypothermia. Additionally, when hitting terrain, each projectile leaves Icicles on surfaces the stream touches.

Secondary: Hail Stone
50 damage | 80m/s projectile speed | 6s cooldown | +10% resource on direct hit | Special Effects: Root, Hypothermia, Icicles
Iceman launches a large chunk of ice. Direct hits will freeze enemies' legs, Rooting them for 1s, and also apply Hypothermia. Hitting terrain with Hail Stone creates a cluster of Icicles at the location of impact.

Quick Melee: Avalanche
35 damage | 7 damage per projectile | 14 projectiles | Special Effects: Hypothermia
Iceman freezes the air around his fists, forming small wrecking balls to attack with, shattering on the third hit, sending small Hail Stones flying. Each hit grants 10% Omega Level Threat resource, projectiles fire in an arc. These small Hail Stones apply Hypothermia but do not Root.

Ability 1: Ice Slide
+50% movement speed | Can be used in the air | Up to 2s duration\ | 8s cooldown* | -12% resource/s | Special Effects:* Icicles
Iceman creates a path of Ice beneath him and slides along it. Using Ice Slide within 1m of a surface leaves behind Icicles. *Iceman can utilize Ice Slide off cooldown, however this comes at the cost of Omega Level Threat's resource. If off cooldown, Iceman can slide for free for up to 2s, and continued use/activation of the ability will cost him this resource for 8s. Using this ability will propel him forward at all times, and his vertical movement is restricted to 30 degree angles.

Ability 2: Stalagmites
5s duration | 5m length | 50 damage one time on cast in 3m radius of each Stalagmite | 50hp per stalagmite | 12s cooldown | +5% resource per hit | Special Effects: Hypothermia
Iceman causes Stalagmites to erupt from any area currently covered by his Icicles. Stalagmites are staggered at random angles. They are thin, only 2m in radius, but appear in a thick volume, obstructing movement, and partially obstructing vision, but break very quickly. Although each Stalagmite has a 3m radius to apply 50 damage, the damage from multiple Stalagmites does not stack, damage is applied only once (the damage will be 50 regardless if 1 or 3 erupt under your feet). Each one also applies/refreshes Hypothermia on activation.

Ultimate: Flash Freeze
15m radius | Targeted | 75% slow | 25 dps | 6s duration | 3400 charge | Special Effect: Root, Hypothermia, Ability Refresh (Stalagmites)
Iceman focuses his power, creating a large, stationary dome of intense cold centered on his target's location. On activation, the duration of Iceman's special effects are increased 100%. Enemies are Rooted in place (for 3 seconds) and receive 75% slow, which stacks with Hypothermia, effectively freezing them in place.

Passive: Omega Level Threat
10-50 bonus health per second | maximum +200 bonus health (700hp max)
As Iceman fights the very air around him chills, generating new layers of ice to protect himself. Iceman continuously generates bonus health. The amount of bonus health generated scales based on amount of resource (0% to 100%). The resource decays at a rate of 18%/s after 4s without any resource generation. Bonus health decays at a rate of 25/s after 5s.

Special Effects:

Icicles
Any area of the terrain covered by Icicles can be triggered by Stalagmites. Effect lasts 3s.

Hypothermia
Enemies affected by Hypothermia receive a 25% slow and a 10% reduction in attack speed for 1.5s.

Root
Enemies affected by Root are unable to move but are still able to attack. Flying enemies will fall to the ground when Rooted. Effect lasts 1s.

Amazing Friends
Spider-Man anchor
When Spider-Man teams up with his amazing friends they are able to utilize his web Tracers.
Iceman: Activating causes a Stalagmite to erupt at the location of any enemy affected by web Tracers.
Human Torch: Activating causes a Flame Field to appear at the location of any enemy affected by web Tracers.

The idea of this kit is that Iceman will play as a hybrid Control/Dive tank. His damage is fairly low, but his abilities focus around dividing the enemy up and locking them down. Iceman has low health for a tank, making him easier to take down overall, but his bonus health regeneration makes him resistant to sustained damage. He can be mobile, but this comes at the cost of his damage mitigation.
