Grampa

Grampa is a boss in Slender Fortress, currently residing at Disc-FF's Slender, Demon Hamster's SF2 Server, and NxN Nameless' SF2 Server.

Description
Hailing from the Garry's Mod Pill Pack known as the "Vagineer Pill Pack", Grampa is a Vietnam War veteran with a possible case of PTSD. Said PTSD is likely the cause of his cannibalism. As weak as he looks, his trusty machete does the job perfectly, along with some protection thanks to his vintage American-made M1 helmet with a spade decal. He's mad, hungry, and certainly senile.

In Slender Fortress
Old Versions: Simply put, he was a generic chaser with no defining traits to make him stand out from other chaser bosses. He had moderate speed, moderate persistency, moderate everything. He even sported a single copy and was able to be stunned. His attack, however, did massive damage, enough to kill light classes in one shot.

New Version: After finding his machete and helmet, Grampa's ready to head back into the battlefield with some new tricks. Instead of being a typical chaser, he aims at being a Survival chaser. Although rather slow, he makes it up in high persistency. He is able to swing his machete fast and efficiently, dishing out moderate damage with a bleed effect. He can further up the damage thanks to his ability to silently mark players on scare. Should he get stunned, it lasts for about 3 seconds and a half, but in return, slightly increases his speed and stun HP, making him deadlier to come across. On higher difficulties, the bleed effect from his attack is extended, as well as gaining access to "guerilla warfare tactics", which in actuality is cloaking. Cosmetically, on higher difficulties, his run animation changes from fast-walking to sprinting.

Trivia

 * Grampa has been a boss since 2015. At best, he was a broken and extremely generic chaser.
 * In 2017 and 2019, he was brought back with some fixes, but was still a very generic chaser that didn't stand out.
 * In 2020, he has since been properly revived with some new tricks, as well as obtaining his machete and helmet.
