This isn't going to be very well written, so please try to bear with me.
Strength/Durability
Season 1-3
So firstly, the
9-A feats from Season 1. In Smallville Season 1, Episode 12,
Clar withstands a truck explosion at a great range and is bruised by the debris. In
Season 1, Episode 21, the same kind of explosion barely affects him. They even mention this outright
- Clark: (Still descending the stairs) What do you think caused the explosion?
- Jonathan: Son, my guess is it was a leaky fuel line. The fumes must have ignited the fertilizer in the back of the truck. I'm sorry. I should have checked it better.
- Clark: I'm just glad I was in the cab and not one of you guys.
- Martha: (Hugging Clark tightly) Oh, sweetheart!
- Clark: The truth is, I barely felt the heat this time. And the debris didn't leave any bruises. Martha and Jonathan share a concerned look.
- Martha: As you get older, your body must be getting stronger.
Contex: The car was rigged to explode by Roger Nixon. It wasn't due to the fuel line.
That car was a 1988 GMC Sierra, and its explosion would produce energy equivalent to
0.0356106597 Tons of TNT. Even if the tank was only partly full, Clark didn't tank the full explosion, etc, it would still be
Small Building level, especially since Jonathan says there's other combustibles and flammables in there.
Season 4/5
In Season 2 and 3, he's definitely stronger but has virtually no feats, so let's move on to Season 4. In
Commencement,
Clark tanks a meteor. The average male shoulder width is
0.4 meters and this was slightly smaller, so I'll assume its 0.3 m. The minimum speed of a meteor within the atmosphere is
11 km/s, so that impacted with
0.6 Tons of TNT, which is
Building level.
These ratings are consistent with another feat in
Hidde in Episode 3 of Season 5, which is takes place mere weeks after
Commencement. In this episode,
Clark withstands the shockwave of a nuclear bomb powerful enough to destroy the town of Smallville. He also tanks the ensuing fall.
Season 6-10
Now, finally the At least
Large Country level ratings; Clark is scaled to Brainiac, whose power source (the black box) contains enough energy to destroy "half a continent". Firstly, the black box powered Brainiac indefinitely, and after its removal he relied on impermanent sources of energy, so his strength would not scale. Second, this same energy from the same episode as the "half a continent" quote
killed Raya within seconds, and that likely wasn't the full power of the black box since Baern wasn't drained instantly. Lastly, Clark was unsure if the Crystal of Kal-El could even hold Baern at this power level,
despite it holding Zod. It was successful, however, but it really goes to show the audience how powerful this guy is.
- Raya: Everything except the training your father wanted for you.
- Clark: So, why are we here?
- Raya: Baern is too dangerous to attack anywhere else. With the power he absorbed from the box, he could wipe out half a continent.
- Clark: If he's that strong, will the crystal still work?
- Raya: It should, provided we stay alive long enough to use it.
I'm not saying he shouldn't be
Large Country level, just that he shouldn't be "At least"
Large Country level.
Season 9 Clark is also a lot stronger and faster than his Season 6-8 self. In early Season 8,
Clark is oneshot by Faora, yet he's comparable to Zod and other Kryptonians of similar strength by Season 9.
Lifting Strength
Clark actually has a couple of feats that place his early lifting strength in the Class 25 range. Also, these aren't outliers since his feats of lifting cars are absolutely casual.
In
Vortex,
Clark lifts a mobile home with moderate effort. I'm fairly sure this should weigh more than 10 tonnes. In Perry,
Clark tosses a tractor across the Kent's farmland.
Speed
This'll be covering everything from Season 1 to 5, not 6-10.
Season 1/2
In Season 8,
Abyss, a flashback to the eight grade shows that Clark could run from his loft to a library in Smallville within seconds. However, this seems like a major outlier.
In
Hug,
Clark appears to be much faster than a bullet. In this same episode,
he moves a bit faster than a bullet to save a man. In Season 2,
he melts a bullet in mid-flight, and in Season 3
he very casually catches a kryptonite bullet. This is very consistent with Clark casually moving at FTE speeds throughout Seasons 1 and 2.
In Season 2, Episode 8 Ryan,
Clark runs from Smallville to Hub City (425 miles) in a matter of minutes. Even if he took 10 minutes, this would still be in the
Supersonic+ range.
Season 4/5
In
Void,
Clark runs from Kansas to Honduras in 10 seconds. This is consistent with Hidden, where he sees a nuke capable of leaving the atmosphere in slow motion.
