Corrupted Valkyrie (反逆のヴァルキリー Hangyaku no Varukirī, Rebellion Valkyrie) is the Boss of Into the Future: Chapter 2.
This enemy has large amounts of HP and attack damage, plus area attack. She is tough to defeat, and when her HP gets to 40%, she increases her attack power by 100%, meaning she deals 14000 damage in one hit. She also has long range (350), meaning that Cats like Necromancer Cat or Swimmer Cat won't be of any use against her as they have less range. The only debuff you can put on this enemy is Slow by using Psychocat (365). When using Uber Rares or Bahamut, good meatshielding is very important for them to avoid getting killed. Any anti-floating or anti-alien Ubers can make her easier.
It is strongly recommended to collect ALL the anti-alien treasures before fighting her. Don't forget that the displayed stats imply you have ALL of those treasures, otherwise she has a 700% buff in attack and health.
With no treasures, she has a whopping 3,888,885 HP and 49,000 DMG, making her almost impossible to defeat without anti-alien Ubers.
With all the Chapter one treasures, she has 2,777,775 HP and 35,000 DMG. Still insanely hard to win.(One-shot kills all meatshields)
With all the Chapter one & two treasures, she has 1,666,665 HP and 21,000 DMG, making her tough, but still possible to beat. However, you will have to deal with this power first before you get the Chapter 3 treasures. Now we're talking.
However, she will be much easier to beat with all the Chapter one, two, and three treasures; she will only have 555,555 HP and 7000 DMG, making her more manageable, easier and faster to beat.
As of update 5.6, her HP has been nerfed by approximately 7.5%, down to 555,555. She has also gained a 5f attack delay.
