I see a lot of this stuff in softcore fiction or high fantasy. A character or alien has some kind of bind or whipping ability, Either it's ribbons, bandages, Tentacles, Chains, vines, etc. Usually, starts with
"Take gun away, grab them by the leg and hang them upside down"
In some instances where the whip, chain, tentacle, ribbon, etc. Is in use. This is justified because of some kind of magic source that enhances and weaponizes the movement.
Though for a hardcore Gene-splicing setting, where a folded tentacle is attached to the wrist with specialized muscles inside to enhance movement, no suckers or anything unless it is at the tip. really be practical as a close combat weapon or utility use like we see in the movies?
Binding people's necks, legs, torso, Taking away their weapon, a stinger on the tip to venomize, stab, Pinch etc.
If this biological weapon did exist. What would be the pros and cons compared to traditional leather whips?
