93IV Larvitar hatched asset or liability

I would, but if you need candies for something else don't feel bad about switching briefly. 545 km is a long journey and you'll probably hatch another by then

Or check a map site like silph road - if a larvitar nest pops up near you, head over there and go to town, using pinap for weaker ones.

I have a similar Larvitar I got on the second day of Gen 2. So far i'm up to 44 candy so a long way to go but I'm just thrilled to finally have a chance for a top tier mon. I have never hatched a Snolax and Dratini are not available in my biome. Therefore I have been relying on Vaporeans and Rhydons for most of my gym action. Finally got the candy to evolve my first Gyarados but got Twister :(

I did. It didn't take near as long as I thought it would since Larvitar seem to be about one of every ten of my 10K eggs. In the time that I hatched 6 Larvitar I hatched only one Mareep and Lapras. It's not as rare as Lapras, Snorlax, and Dratini seemed to me were when I started.

I know this, I'm never buddying a Dratini again.

I would keep it, but not walk it unless there was nothing else more useful I could walk - save up candies from hatches and catches until you get it.

A blissey takes fewer candies, so less walking distance, and is better. Tyranitar is a decent attacker, and a passable defender. Blissey is an metagame-defining monster on defense; two snorlaxes stacked ontop of eachother. There are so many good attacking options, it's hard to justify such a huge walking expenditure for something that only shines on offense; a godly defender like blissey is an easy choice.

Its your choice, but I have caught plenty of Larvitar myself (hatched 1 too) and none of them have had such great IVs, so I am personally jealous of yours and would love to evolve it.
Chancey for me is rarer and thats who I walk with
