Underfell Frisk

Before the "Papyrus Update" It is the weakest thing on the "Chara" team it has stick and 20 health, nothing special about it and no upgrades. Often used for handing out wins for the "Sans" team. Although it is fragile it is known as a glass cannon after the "Papyrus Update" it's ATK ranges from 15-99, It's hp ranges from 20-92 and it can heal (if you upgrade it)

Upgrades

Flowey: Gives 32 hp, toy knife and Flowey Who drops friendlyness pellets(which heals 5-8 hp)

LV 8: Gives 52 hp, Torn notebook and makes Flowey Head(on the top half)half HATE covered

LV 19: Gives 92 hp, real knife and makes flowey completely covered in hate

Other

Despite being possibly the biggest grind to get, it's a very bad reward. 92 hp, real knife and a bit of healing.

Tactics
As flowey has the ability to heal teammates, it's a priority to make sure you can stay alive to heal them more often. Only go for hits that you are sure will not take a lot of damage. As sans, you can attack the pellets that the chara is trying to get to have free damage.
