Fenix by Squiddylicious

When Fenix Health is below 25%, his Basic Attacks deal additional damage and his Primary Abilities have their Cooldowns significantly reduced.

Skillshot.

Fenix slashes enemies in front of him with his Psi blades for moderate damage, dealing more damage to stunned targets.

Fenix gives himself a short-duration buff that will greatly reduce damage from the next incoming enemy ability or attack. Nearby friendly minions and mercenaries gain a less effective version of that buff.

Automatically charges at the closest visible enemy at increased movement within a moderate range (Heroes prioritized) and stunning them. Has a very short cooldown. 

Skillshot.

Fenix shoots with his Phase Disruptors, dealing significant damage to enemies within area of effect. Targets are also stunned for a short period of time.
This ability can be charged up to increase stun duration and damage.

Using juryrigged Immortal technology, Fenix automatically gains a moderate sized shield for a short duration whenever dealt a moderate amount of damage. Fenix can activate Hardened Shields for an even greater shield that lasts longer, but the automated shield function will be disabled for a period of time.

Automatically leap towards the closest visible enemy within Basic Attack range (Heroes prioritized), stunning them and nearby enemies in addition to dealing great amount of damage to them.

When Fenix dies, permanently change into Dragoon form. In Dragoon form, Basic Attack is ranged and deals splash damage. Fenix primary abilities are permanently changed into their more powerful Dragoon form equivalents, but Dragoon Fenix has no Heroic Ability. Respawn time is significantly reduced.

For a short period, Fenix takes significantly less damage from enemies and deals additional damage through his Basic Attacks. His primary abilities have double charges. If Fenix dies while Last Stand is active, nearby enemies become vulnerable for a short period of time.

As a Dragoon, Fenix has a minor permanent increase in movement speed as opposed to using a Mount.
