Beast Out

Beast Out is when MegaMan.EXE absorbs a Cybeast, either Falzar which is a large hawk/phoenix or Gregar a wolf to become Falzar/Gregar Beast MegaMan you can see these forms in the games MegaMan Battle Network 6 Cybeast Falzar/Gregar. Also MegaMan can do cross form (it's similar to Double Soul but longer) with Beast Out. Both of these forms have great might, and can be used effectively. In the games, after Beast Out is introduced, it can be triggered by using the Beast Button, located just underneath the "OK" button in the Custom Screen. A counter appears in MegaMan's emotion window - this shows how many turns his Beast Out will last if used. Battling without initiating Beast Out will refill the counter by 1, to a maximum of 3.

During Beast Out, MegaMan gains several abilities, inclusive of a rapid-fire buster, and chips being auto-targetted so short-range chips become more useful. He can also charge non-elemental chips to unleash the Beast Out's special attack. When used with a Cross, this forms a Cross Beast, with the benefits given by the Cross and the Cross Beast having its own unique special attack. Beast Out can also utilize Full Synchro.

Gregar Beast Out
Taking form of the Cybeast Gregar, Megaman gains an extremely fast-firing buster, along with Super Armour, allowing him to execute attacks without the worry of being interrupted by taking a hit. Non-elemental, non-dimming chips gain +30 damage, and the chip charge attack is a double claw slash that hits for 60 damage each, increasing by 10 damage for each increase in Buster attack.

Falzar Beast Out
Taking form of the Cybeast Falzar, Megaman gains a fast-firing buster that fires down his entire row along with covering 2 columns of 2 rows beside, along with Air Shoes and Float Shoes, allowing him to move over any panel without harmful side effects. Non-elemental, non-dimming chips gain +30 damage, and the chip charge attack is a double claw slash that hits for 60 damage each, increasing by 10 damage for each increase in Buster attack.

Beast Over
When a Beast Out or Cross Beast expires due to the emotion counter running out, MegaMan enters a Tired state. In this state he cannot achieve Full Synchro, though he can still use Crosses. He also gets an option to use Beast Over. In this case, MegaMan becomes fully uncontrollable for the following turn, turning invincible and randomly jumping about, firing the buster, and using loaded chips with double the power. When the Custom Gauge fills, Beast Over immediately expires, forcing MegaMan into an Exhausted state, where his Buster stats are reduced to 1 each, gets an HP bug which rapidly removes health at a quickened pace (to the point where Megaman can have 1 HP before the custom bar can fill the following turn), and cannot enter any other emotional state.

Anime
In the anime, MegaMan's Beast Out can only be triggered when he is in a dangerous situation while Trill is around. The Beast Out transformation cannot be controlled, sending MegaMan on a rampage, attacking both friend and foe until the transformation is forcefully canceled. In Beast+, MegaMan can utilize Beast Out through Beast Out chips, and in this state he can control the transformation. Also, with help from Trill, Megaman can combine both Beast Outs to form the "Juuka Style", an invincible Megaman with the powers of both Cybeasts.
