Spike is a dwemer sphere follower with its own custom framework. For now, Spike has 282 lines and will mainly comment during the vanilla factions and main quest. When I eventually get more time, I want him to comment on all the other major quests in the game.

You can find Spike beside Calcemo in Markarth.

What he comes with is:

different combat styles

• Ranged
• Melee
• Balanced
  

Main quest commentary
quest commentary for the College of Winterhold
quest commentary for the Companions
Thieves guild commentary
Dark Brotherhood commentary
comments about cities and areas*

Daedra quests:
The only cure
A night to remember
The mind of Madness
House of Horrors
The cursed Tribe
The break of Dawn
The Whispering Door

Sidequests:
Lost to the Ages
Missing in Action
The Blessing of Nature
In my time of need

Quest location covered:
Whiterun

Collabs:

About Spike's arsenal:
Aside from being a normal dwarven sphere, he is equipped with a custom crossbow.

The crossbow is enchanted with poison and has a set of explosive lightning arrows. If you equip him with an empty soul gem, he will automatically fill it when he kills something with the crossbow. You can equip Spike with other arrows, but he will have a quiver floating around him due to his body not being a humanoid.

He has an ability to turn on a shock cloak in combat, and his attacks are laced with poison.

If you want to go with a stealth build, he can turn invisible whenever you sneak around. The light component will only turn on during nighttime or when you are in dark caves. Furthermore, it will also turn itself off when you sneak.

In addition, he can equip armour as well, further boosting his defence.

Finally, he has a teleport to you spell in his inventory.

In concern to the balance of the game
creatures in skyrim cannot block, thus spike will be pretty vulnerable in higher levels.

Plans:
Expanding general commentary*
