Lightning Grease and the Bitter Roulette

Formerly the Familiar of Spring, Julian fought so bravely to defend his Season, that even the Mach Force was stunned by his loyalty. But his own ideals and that of the wizard collided when he was tasked with finishing the job, ending their partnership and earning the Mach Force a new ally.

Winter was the only one of the Seasons to relinquish is rule willingly. Seeing himself an overseer of the cycle of death and rebirth, he held a wisdom and vision the other three Seasons lacked. After the battle, some say he continued his work in secret as the Grim Reaper.

Doubt is one of the more insidious of the lesser Intruders. It latches onto the victim's chest, growing and weighing them down until their body acts like a crawling shield for the parasite itself.

A mechanical lifeform from beyond the sky, Rollblade was captured and experimented on by the Seasons before the Mach Force could rescue him. Now he fights back against his former oppressors alongside his newfound allies.

Olympia had been a thorn in Summer's side even before the rebellion. Initially untrusting of Doctor Rocket's motives, she would eventually become an ally to the Mach Force after baring witness their resolve.

Jeel, the Emerald Dragon, was on of the first to join Doctor Rocket's Mach Force and battle the wizard council. Lacking the magic prowess of the legendary Golden Dragon who trained Farren, she augmented her power with Rocket's technology.

Some believe Lash is the final stage of a Nagging possession, but the metamorphosis as yet to be observed. Whatever the case, this Intruder has abandoned even its most basic survival instincts to destroy as much as it can with its flexible, bladed arms.

Almond and Hazel used to call him Mr. X.

If Mirth's job/hobby wasn't so dangerous, she would NEVER shut up about her kids.

The Prince was the old order's final hope, and the scourge of those trying to throw off their shackles in the world to come.

Sometimes, maybe, a dream really could come true.

Later Artificial Familiars were conjured for pure combat, to better deal with the new type of arcane combat the Sorcerists had developed. These were typically enchanted with powerful weaponry and extremely high speed.

Farren's rebellion days may be long past her, but magic never fades away. 

Artificial Familiars came into vogue after Farren's rebellion. Though early prototypes lacked the ability to perform complex tasks, their unwavering dedication to their masters made them formidable in large numbers, even after those masters were gone.

Autumn's reign ended when he incited the wrath of his familiar. The remaining seasons faced the full rebellion not long after.

Intruders are inherently parasitic, but none as blatantly as the Nagging. Eroding the host's sense of identity, they lash out at any who get too close.
