Backstory: In the world of Tekken there are tons of fighters across the world of Tekken but none like the Jack robots. Russia created Jack for the sole purpose of destroying targets thanks to the provided by Mishima Ziabatsu.

Feats(Strength and Durability):

-Jack 2 tanked a laser from a satellite

-Jack 3/Gun Jack tanked the same satellite that destroyed Jack 2

-Jack 6 destroyed a 6 mile asteroid that is powerful enough to be

-A bunch of Jack 4s blew up Heihachi

-Comparable to Feng Wei

Feats(Speed):

-Jack 6 Flew from Earth to the asteroid in seconds

-Gun Jack reacted to the satelite laser by making a forcefield

Feats(Strength and Durability):

-Multipliers

>Since the Jack 6 model is 10x stronger than the previous model I am gonna use a 10x multiplier for each of them as well as diving them for earlier models

-Destroying a meteor

>Last time on Battle Match, I calculated Jack 6's power to be 31.1 teratons however since the meteor that Jack 6 destroyed is the same size as the one that killed the dinosaurs it would be around 310 teratons to 14 petatons

>Note: I will use Jack X from Street Fighter X Tekken since Leopold used Jack X in his videos

>31.1 x 10 x 10 x 10 = 31100 teratons or 31.1 petatons

>310 x 10 x 10 x 10 = 310000 teratons or 310 petatons

>14 x 10 x 10 x 10 = 14000 petatons or 14 exatons

>Jack 5: 14,000 / 10 = 1400 teratons or 1.4 petatons

>Jack 4: 1400 / 10 = 140 teratons

>Jack 3: 140 / 10 = 14 teratons

>Jack 2: 14,000/10 = 1400 gigatons or 1.4 teratons

>Jack 1: 1400 / 10 = 140 gigatons

>P. Jack: 140 / 10 = 14 gigatons

>In the Jack 1 model is Large Island Level at best

-Satellite laser feat

>In this ending:

https://youtu.be/Ld74he-Ut84

>The satellite killed off Jack 2 and Jack 3/Gun Jack in Tekken 3 made a forcefield that protected him from the blast from the satellite

https://youtu.be/G7-aS8K6g1o

>The force of the sattelite was 79 megatons of force, however the forcefield surrounding Gun Jack saved him and Jane, not Jack himself meaning that despite being 10x stronger than Jack 2 he can't tank the hit which means the forcefield is 100x stronger than Jack himself

>79 x 100 = 7900 megatons or 8 gigatons which is Island Level

>Assuming that the forcefield is carried out to later models of Jack

>8 x 100 x 100 x 100 x 100 x 100 x 100 = 80,000,000,000 gigatons or 8 Zettatons

>And applying the multiplier to the Asteroid feat done by Jack 6

>14 x 100 x 100 x 100 = 14000000 petatons or 14 zettatons which is Small Planet Level

-Pachinko Meteor Scaling

https://youtu.be/L7CJ-Z75lYM

>In the Japan exclusive Pachinko Machine based on the events of Tekken 7

>According to Leopold, Marshal Law and Paul Phoenix deflected a meteor in 1 second that is 36x bigger than the one Jack 6 destroyed which is worth 20 Zettatons

>And since Feng Wei managed to beat both Law and Paul and Jack is comparable to the guy

https://youtu.be/G4HLqH9zLBE

>20 x 3 x 10 x 10 = 6000 zettatons or 6 yottatons Large Planet Level

>As for the forcefield stats

>20 x 3 x 100 x 100 = 600000 zettatons or 600 yottatons which is Large Planet Level

Stats(Speed):

-Flying to the meteor

https://youtu.be/v-aP0UOKzz8

>In this ending, Jack 6 flew from the Earth to the meteor in 13 seconds how ever the distance is not clear but considering that Jack 6 burns up upon re-entry into Earth's atmosphere and the point of burning by re-entering Earth's atmosphere is the Mesosphere which means that between Point A(Earth's surface) to Point B(Meteor) is 6,214 miles. That's 1720800 mph or Mach 2260 which is Massively Hypersonic

>1720800 x 10 x 10 x 10 = 1720800000 mph or 3x the speed of light

-Scaling to Kazuya's laser

https://youtu.be/vsBLARuKdOE

>Last time on Battle Match, Kazuya's attack speed with his forehead laser is 67x the speed of light or 44930200000 mph and characters like Heihachi can intercept it

>And since there are mutliple instances where Jack robots fought Heihachi and other comparable characters

https://youtu.be/yU3NKqO_LP4

https://youtu.be/000hndfXVUo

>Since a dozen Jack 4 units can move fast enough to hold Heihachi down

>44930200000 x 10 x 10 x 10 x 10 x 10 = 4,493,020,000,000,000 mph or 6700000x the speed of light

-Gun Jack blocking a laser

>the distance between the laser and Gun Jack is 39999 km or 24854.226 miles and it took 2 seconds for the laser to hit Gun Jack

>That's 44737607 mph or Mach 58772 which is Sub relativistic+

>44737607 x 100 x 100 x 100 x 100 x 100 x 100 = 44,737,607,000,000,004,096 mph or 66712804951x the speed of light

Final Verdict: MFTL+

Weaknesses:

-Despite getting improved after every model, the Jack series of robots are cannon fodder compared to guys like Heihachi, Akuma, and Jin

-Self destruct move won't work on foes like Hehachi who can survive it

-Only relies on Bruteforce which leads to him being taken down by much more skilled opponents 

Possible Opponents:

-Jasper

-Genos

-Jenny Wakeman

-Robot Boy

-E-123 Omega

-Android 16
