Bouncing Battler: He rolls into a ball and bounces around the room.
Once his armor is shorted out, however, so is his invulnerablity.
Boss Vulnerability: He is only vulnerable when he is firing, or after he finishes his Rolling Attack.

Turns Red: They'll modify their pattern and whip out new strategies after their health goes below half.
For example, Chill Penguin slides on the floor, Wheel Gator does the alligator death roll, Blast Hornet attacks with his stinger, etc.
Stock Animal Behavior: Many of the Mavericks have an attack based on a behavior of the animal they're based off.
This is shown the most in X6 (see below) where the names mostly don't change overseas you'd be hard pressed to find out what "Mijinion" would refer to.
A Lizard Named "Liz": Meanwhile, in the Japanese version, the bosses' names are corruptions of the name of the animal they represent.
Unlike the Robot Masters in the Classic series, several Maverick bosses can have the same "Something" word in their names, such as Flame Mammoth, Flame Stag, and Flame Hyenard.
Something Person: Generally it's " Something Animal" (with occasional plant and fungus).
Red Baron: Most, if not all of them have one each.
Playing the Victim Card: Some play this trope when they aren't Brainwashed and Crazy.
Monogender Monsters: All of them are male.
Fire Is Red: When you encounter a fire-based Maverick, expect them to be colored red or orange.
Four-Legged Insect: Most arthropod-based Mavericks just have two arms and two legs.
Heel≯ace Turn: In the manga at least, several Mavericks can recover their senses and turn good again.
FaceHeel Turn: Many of the Mavericks you fought are former Hunters or otherwise-neutral civilians.
It gets egregious in the original X5 where the western names of the Mavericks are references to Guns N' Roses members.
Dub Name Change: Many bosses have their names changed in the western release, with the Maverick themselves was known as Irregulars in the Japanese version.
Especially in case of Spark Mandrill who can be prevented completely from moving at all with his Weakness weapon, Shotgun Ice.
Cycle of Hurting: In many cases, using their Weakness weapon will make their AI trapped in a loop that makes them vulnerable to another Weakness weapon attack.
Brainwashed and Crazy: Due to the Sigma Virus, for most cases, although it's shown most prominently in X3 and X5.
Beast Man: The majority of these Mavericks are Ridiculously Human Robots that resemble animals.
